JEROME R. GEORGE, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO MORGAN CON-STRUCTION COMPANY, OF WORCESTER, MASSACHUSETTS, A CORFORATION OFMASSACHUSETTS.

GAS PRODUCER.

Application led July 1, 1915.

To all whom t may concern:

Be it known that I, JEROME R. GEORGE, a citizen of the United States,residing at lVorcester, in the county of Worcester and Commonwealth ofMassachusetts, have invented a new and useful Improvement in a GasProducer', of which the following, together. with the accompanyingdrawings, is a specification.

The present invention relates to gas producers, and has particularreference to an improved construction by which the discharge of ashesfrom the producer is facilitated, and by which the blast of air, or airand steam, used to support the combustion of fuel in the producer isintroduced and distributed at the level of the ash supporting surface.

The features of my invention are fully set forth in the followingdescription and pointed out in the annexed claims, reference being hadto the accompanying drawings, in which- Fig. 1 is a vertical sectionalview of a gas producer embodying my invention, the section being takenon line 1 1, Fig. 2.

Fig. 2 is a horizontal sectional view on line 2 2, Fig. 1.

Fig. 3 is a fragmentary plan view of the bottom of the ash support, and

Fig. el is a detail sectional view on line elf-ll, Fig. 2.

Similar reference characters refer to similar parts in the differentfigures.

The gas producer embodied in my invention contemplates a rotatable mainor fuel section 1, within which the level of the bed of fuel ismaintained at or near the line 2, Fig. l. The combustion chambersurrounded by the section 1 is enclosed at the top by a stationary coversection 3 having a depending apron L t which projects into an annularwater jacket 5 surrounding the shell of the main or fuel section 1, toprovide a water seal against the escape of gases from the combustionchamber. The cover section 3, which is supported from posts 6 or thelike, provides the usual conduit 7 for conveying away the gases producedwithin said chamber, and also provides the usual opening 8, having aremovable cover 9, to pernnt the replenishment of fuel within saidchamber.

Serial .'No. 37,571.

edge of the fuel section 1 is a circular water pan 10, from the edge ofwhich depends a preferably integral, annular ash trough 11. To the underside of said trough is attached an annular bevel gear 12, which alsoprovides an annular track 13, by means of which the water pan 10 isrotatably sup ported upon a plurality of rollers 14, in the presentinstance three in number, one of which is shown in Fig. 1. The water pan10 provides a plurality of shelves or lugs 15, in the present instancethree in number, one of which is shown in Fig. 1, and each shelf or lugsupports a column or post 1G rigidly attached at its upper end to aflange 17 carried by the shell'of fuel section 1. In this manner thefuel section 1 is supported by, and held spaced away from, the water pan10, the two parts being adapted for rotation in unison, in the mannerhereinafter specified.

The water pan 10 provides a central upstanding hub 18, and also aplurality of concentric annular upstanding partitions 19, E20 and 21,which are gradually reduced in height toward the outer edge of the pan.In this manner a series of annular water chambers Q2, 23 and 24; areproduced, within which the cooling water is maintained at differentlevels, as shown in Fig. 1. The ovcrfiow of water from the water jacket5 is received by a pipe 25, communicating with one of the columns 16,Fig. 1, which is made hollow for this purpose. The lower end of saidcolumn 16 is connected to a horizontal passage 26, formed on the bottomof the pan 10 and passing under the several partitions 19, 20 and 21,opening into the innermost and deepest water chamber 22. The overflowfrom each water chamber supplies in turn the next adjacent shallowerchamber, and the overflow from the outermost and shallowest chamber 241passes into the concave trough 11 formed on the edge of the water pan.It is to be understood, of course, that any numb-er of water chambers,arranged as above described, may be provided in the water pan.

The gradual outward descent of the series of annular partitions 18, 19,20 and 21 provides for the support thereon of an annular plate 27,frusto-conical in form, which serves as the fuel and ash supportingsurface of the producer. Said plate 27 is atof one of these columns canbe accon'iplished Without providing any temporary support for the fuelsection, and the ash support and blast structure can be removed throughthe space thus made available.

The Water jacket 5 of the fuel section is formed by spaced inner andouter plates surrounding the usual lire brick lining. An annular plate52, forming the bottom of the Water jacket, has a substantiallyvertically disposed portion 53 to which the innerjacket plate issecured, and a horizontally disposed shelf 54 providing for the erectionof the brickwork thereon. The outer Water jacket plate being attached.to the inner Wall of trough 5l, it will be clear that the constructionshoivn and described avoids the necessity for Hanging the plates Whichare used to form the bottom and sides of the Water jacket.

The ashes crowded into the rotating trough 1l by the arms 34 may beremoved therefrom by the use of a stationary inclined blade 55, F ig. l,in the manner common to devices of this class. The constant rotation ofthe section 1, containing the bed of fuel, enables the use of a fuelevener 56, of a type known in the art, requiring a relative traversingmovement between it and the bed of fuel, for levelling the surface ofsaid bed.

By the arrangement and disposition of parts shown and described, whichmakes it possible for the blast to be discharged at the level of the ashsupporting surface, a producer of much less height than the ordinarytypes of mechanical gas producers is Drovided. The support provided forthe ashes is entirely dry at all times, in distinction to producers inwhich the ash pan utilized in the formation of a Water seal, vet alldanger of overheating' said supportlis absent, owing to the coolingfurnished by the water pan beneath the same. The location of the blaststructure in immediate proximity to 'the ash supporting surface, ratherthan at a distance above the same, as in prior constructions, insures anash bed of uniform character, since there is no obstruction to thepassage of ashes onto the surface of the support.
